Control lots of appliances and other high-power devices with your Raspberry Pi Zero with this industrial 6-channel relay module.

The module is designed specifically for the Raspberry Pi Zero which fits inside the unit via the dedicated header, which is then powered by the board from the included power supply and onboard 5V regulator. Control is managed via the GPIO pins making it easy to create your own relay control scripts. There's also RS485 and CAN half-duplex communication options with screw terminal connections.

Once set up, you can use this module's 6 relays to control ≤10A 250V AC or ≤10A 30V DC devices, great for home automation and similar projects. The module includes photocoupler isolation and power supply isolation, alongside resettable fuses, protection diodes and an onboard TVS suppressing surge voltage.

The tough enclosure is made from ABS, providing a level of physical protection whilst also offering support for rail mounting. The enclosure includes connection information, helping avoid having to open the unit each time for connection changes. Relay and power indicators provide visual confirmation and support debugging efforts.

Comes with a UK plug! Raspberry Pi Zero not included.

Features

  • RS485 half-duplex communication: using SP3485, UART control, auto RX/TX switch
  • CAN half-duplex communication: using MCP2515 + SN65HVD230 solution, SPI control
  • Onboard unibody power supply isolation, provides stable isolated voltage, requires no extra power supply for the isolated terminal
  • Onboard photocoupler isolation, prevent interference from external high-voltage circuit connected to the relay
  • Onboard TVS (Transient Voltage Suppressor), effectively suppresses surge voltage and transient spike voltage in the circuit, lightning proof & anti-electrostatic
  • Onboard resettable fuses and protection diodes, ensuring current/voltage stable output, preventing over current/voltage - better shock-resistance performance
  • High-quality relay, contact rating: ≤10A 250V AC or ≤10A 30V DC
  • ABS protection enclosure with rail-mount support, easy to install, safe to use
